How many such pairs of letters are there in the words ‘COMPLIMENTS’ each of which has as many letters between them in words (both in backward and forward direction) as they have between them in the English alphabetical series?
OL, MT, PM and TS.
How many values of x and y satisfy the equation 2x + 4y = 8 & 3x + 6y = 10.
I. x=  √(20+ √(20+ √(20+ √(20…………….∞)) ) )Â
II. y= √(5√(5√(5√(5……….∞)) ) )Â
...I. 5x + y = 37
II. 4y+ x = 15
I. 8x² - 78x + 169 = 0
II. 20y² - 117y + 169 = 0
I. 20x² - 93x + 108 = 0
II.72y² - 47y - 144 = 0
If α, β are the roots of the equation x² – px + q = 0, then the value of α2+β2+2αβ isÂ
...I. 2y2 - 15y + 18 = 0
II. 2x2 + 9x - 18 = 0
I. 2x2 – 10x – 48 = 0
II. y2 – 16y – 297 = 0
I.√(3x-17)+ x=15
II. Â y+ Â 135/y=24Â
I. 20y² - 13y + 2 = 0
II. 6x² - 25x + 14 = 0
